🛠️ Technical Implementation

State Management:

const [selectedImage, setSelectedImage] = useState<string>();
const [selectedVariation, setSelectedVariation] = useState<any>(null);
const [selectedAttributes, setSelectedAttributes] = useState<Record<string, string>>({});
const [quantity, setQuantity] = useState(1);
const [activeTab, setActiveTab] = useState('description');

Key Features:

Auto-Switch Variation Image:

useEffect(() => {
  if (selectedVariation && selectedVariation.image) {
    setSelectedImage(selectedVariation.image);
  }
}, [selectedVariation]);

Find Matching Variation:

useEffect(() => {
  if (product?.type === 'variable' && Object.keys(selectedAttributes).length > 0) {
    const variation = product.variations.find(v => {
      return Object.entries(selectedAttributes).every(([key, value]) => {
        const attrKey = `attribute_${key.toLowerCase()}`;
        return v.attributes[attrKey] === value.toLowerCase();
      });
    });
    setSelectedVariation(variation || null);
  }
}, [selectedAttributes, product]);

Thumbnail Scroll:

const scrollThumbnails = (direction: 'left' | 'right') => {
  if (thumbnailsRef.current) {
    const scrollAmount = 200;
    thumbnailsRef.current.scrollBy({
      left: direction === 'left' ? -scrollAmount : scrollAmount,
      behavior: 'smooth'
    });
  }
};
